To subtract the expression \(2(10b + 4) - (b - 2)\), we first distribute the \(2\) and then simplify.
1. Distribute \(2\) in the first term:
\[
2(10b + 4) = 20b + 8
\]
2. Distribute the negative sign in the second term:
\[
-(b - 2) = -b + 2
\]
Now, combine the results:
\[
20b + 8 - b + 2
\]
3. Combine like terms:
\[
(20b - b) + (8 + 2) = 19b + 10
\]
Thus, the simplified result is:
\[
\boxed{19b + 10}
\]
